How many amps in a circuit with 2 D cells and a resistance of 4 ohms?

A perfect typical D cell is 1.5V (alkaline slightly less) so two cells are 3.0V. The current flow would follow Ohm's law E=I*R or in this case I (current) = E (voltage) / R (resistance) or 3/4 = 0.75 Amps.
Note that D-cells cannot for long supply this much current and the voltage from the cells will be less than 1.5V (due to the cell's internal resistance) and will fall off rapidly as they simply do not have the capacity to deliver this much current for very long.

How many amps does a circuit with 110 volts and a resistance of 7ohms have?
The equation that you are looking for is I = E/R. Amps = Volts/Resistance.
How many amps equal 1 circuit?
80% of the rated circuit. 10 amp circuit is 8 amps, 20 amp circuit is 16 amps, etc.
How Many Amps Can a 30 Amp Circuit Handle?
30 amps
How many amps does 230 watts equal is you are using 120V ac circuit?
1.9 amps
.01 amps equal how many volts?
Amps and volts are not the same, but related by Ohm's Law. Volts = Amps x Ohms. Ohms is a measure of resistance. Given .01 amps you would have to know resistance to calculate volts.
How many amps does a circuit with 110 volts and a resistance of 7ohms have?
The equation that you are looking for is I = E/R. Amps = Volts/Resistance.
How many amps will a 260 ohms resistor on a 120 volt circuit use?
Just use Ohm's Law Voltage = Current x Resistance Amps = Voltage Divided By Resistance Amps = 120 / 260
How do you find voltage when amps is known?
You don't. If you know how many Amperes in an electrical circuit and also what the total resistance in the circuit is, then EMF (Volts) = current (Amps) x resistance (in Ohms). EMF stands for Electromotive Force, and its unit of measure is the Volt.
How many watts is 20 amps?
Twenty amps is zero watts. You are missing one value. W = Amps x Volts. <<>> It depends on the resistance and the draw current in the electrical circuit.
How many amps is a lawn mower battery?
The apmeres depend on the resistance of the circuit. The battery will be a certain voltage, and dividing the voltage by the resistance gives you amperes. V = I*R
How many miliamperes are produced when 4 D cells are in series circuit?
The current in the circuit is(6,000)/(the resistance connected between the terminals of the D cells, in ohms)milliamperes
How many amps equal 1 circuit?
80% of the rated circuit. 10 amp circuit is 8 amps, 20 amp circuit is 16 amps, etc.
How many amps in 120volts and 500ohms?
You use Ohm's Law to make your calculation. Volts = Amps x Resistance Amps = Volts / Resistance
How many amps would it take to kick a 15 amp breaker with 7 ohms resistance on a 277 volt circuit?
A 15 amp circuit breaker should trip at 15 amps regardless of the load voltages or impedances. If you have 277 volts and 7 ohms, the current would be 39.5 amps and a 15 amp circuit breaker should trip.
How will amps and current differ in a series if you get resistors with different resistance?
-- "Amps" and "current" are the same thing. Electric current is measured in units of Amperes. -- The current is always the same at every point in a series circuit, no matter how many resistors of the same or different values are in the circuit.
How Many Amps Can a 30 Amp Circuit Handle?
30 amps
How many ohms is a 120 volts?
"Volts" is electrical pressure applied to a circuit; whereas, "ohms" is electrical resistance to that pressure. One cannot determine ohms from voltage without knowing either the current (in "amps") or power (in "watts"). A normal 120V household circuit can handle a maximum of 20 amps, so using ohm's law of resistance = voltage / current, the minimum resistance required in a 120V household circuit would be 6 ohms. Any less than 6 ohms will cause the circuit breaker to trip.
