What else can I help you with?
What kind of math do you need to be an electrician?
Arithmetic and basis algebra are good skills to have. For example, Ohm's Law says Voltage = Current x Resistance. If you know Resistance and Voltage and want to solve for current you need to know that Current = Voltage / Resistance.
What is the product of current multiplied by resistance?
Voltage
What does the vertical scale on an oscilloscope measusre?
The vertical scale on an oscilloscope measures the voltage of the signal being analyzed. It is typically expressed in volts per division, allowing users to interpret the amplitude of the waveform displayed on the screen. By adjusting the vertical scale, users can zoom in or out on the signal to better visualize its characteristics, such as peak voltage and signal shape.
How do we calculate?
V = I x R V = voltage, I = Current, R = Resistance or it can be calculate like this V = P / I V = Voltage, P = Electric Power, I = Current
How does arc length affect voltage?
The longer you strech the arc, the smaller the voltage. Current rises though.
How can display voltage current characteristics on a cathode ray tube?
-- Connect a diode and small resistor in series across a source of AC. -- Using the point where the diode and resistor meet as a common point, connect one scope probe (H or V) to the far end of the resistor, and the other scope probe to the far end of the diode. -- One dimension of the scope display now corresponds to the voltage across the diode. -- Since the voltage across the resistor corresponds to the current through it, the other dimension of the display corresponds to the diode current. -- I leave you to work out the scale factor for the current, and the various polarities.
When alternating current flows through an capacitor current leads voltage by a phase angle of 90 degrees what is the physical interpretation of this phenomenon?
One interpretation is that if you take a capacitor that is not charged, it needs to take some current before any voltage appears across it. Therefore the current must precede the voltage.
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Can there be a current with no voltage?
No, There can't Be current without voltage
What is the relationship between voltage and current as shown in the graph of voltage vs current?
In the graph of voltage vs current, the relationship between voltage and current is linear. This means that as voltage increases, current also increases proportionally.
What 3 things does an electrical amplifier amplify?
An electrical amplifier amplifies 2 physical quantities according to the transistors used. If a BJT is used it amplifies the current and if a MOSFET is used it amplifies the voltage. Hybrid amplifiers amplify current as well as voltage so in theory , current voltage and power is amplified.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
How is zener diode different from ordinary pn junction diode in its fabrication?
An ideal zener diode will have zero reverse current while the reverse voltage is less than the zener voltage. Once the voltage rises above the zener voltage, the maximum reverse current will become infinite (the device will become a short). On a graph with voltage along the X axis and current along the Y axis, this would be represented by a straight vertical line crossing through the zener voltage. A practical zener diode has a monotonic change from zero current at zero volts, rising gradually as the voltage approaches the zener voltage from below, then rising sharply as the voltage is around the zener voltage. This means that with reverse voltage applied even slightly below the zener voltage there will be some current flow. This can be a problem in some circuits if not understood and accounted for.
Why current leads in capaciter?
Capacitors resist a change in voltage. It takes current to effect a voltage change, resulting in the current "leading" the voltage. Similarly, inductors resist a change in current. It takes voltage to effect a current change, resulting in the current "lagging" the voltage.
How do you find the current if you have the resistance but not the voltage?
The current will be zero if there is no voltage.
What you consume in home current or voltage?
Power is contituted by both current and voltage So we consume both current and voltage
