current flowing into the node are taken to be negative, and currents flowing out of the node are positive. It should not really matter which you choose to be the positive or negative current, as long as you stay consistent. However, it may be a good idea to find out the convention used in your schema

State Kirchoffs voltage and current law?
Kirchoffs Current Law : [KCL]This law is also called Kirchhoff's point rule, Kirchhoff's junction rule (or nodal rule), and Kirchhoff's first rule. The principle of conservation of electric charge implies that: : At any point in an electrical circuit that does not represent a capacitor plate, the sum of currents flowing towards that point is equal to the sum of currents flowing away from that point. Kirchoffs Voltage Law : [KVL]This law is also called Kirchhoff's second law, Kirchhoff's loop (or mesh) rule, and Kirchhoff's second rule. : The directed sum of the electrical potential differences around any closed circuit must be zero.Kirchoffs Laws are widely used in the Electrical and Electronic engineering fields.Hope this helps =)
If the current is 10 amperes in the main wire and 4 amperes in one of the branches how much current is in the other branch?
Six, Voltage is the same in a parallel circuit but current divides to total the sum of each branch. See Kirchoffs current law.
Can kirchoff's voltage law be used to determine voltage drop?
Yes. Kirchoff's Voltage Law states that the signed sum of the voltage drops going around a series circuit is zero. Thus, if you know all but one, you can figure it out. You simply add what you know up, and what is left is the last drop. Don't forget to be consistent in your use of signs. If, for instance, you show a voltage or current source as a voltage rise, then it must be considered to be a negative voltage drop. Or vice versa, as the case may be.
Will you get a electric shock when the negative terminal of the dc power supply is grounded and the positive terminal is held by us?
Only if we are also in contact, directly or indirectly, with ground. By ohm's law, current is voltage divided by resistance. Conductance is the inverse of resistance, so current is voltage times conductance. No conductance - no current.
Using Ohm's Law explain how voltage changes in relation to current assuming that resistance remains constant?
how do you use ohms law express conductance in terms of current and voltage?
What is kirchoff voltage law and kirchoff current law?
kirchoffs voltage law : the algebric sum of all voltage drop is equal to algebric sum of voltage risekirchoffs current law : algebric sum of all current entering at a node is equal to algebric sum of current leavingCommentIt's Kirchhoff, not 'Kirchoff'!
What is the application of kirchoffs voltage law?
Kirchoff's Voltage Law: The sum of the voltage drops across all elements in a series circuit add up to zero. If you know the voltage drops across all but one element, and you know the voltage rise across the source, then you can easily calculate the remaining drop.

Why terminal potential difference is decrease when current in the circuit is increased?
If the terminal voltage decreases when more current is drawn, that is due to the internal resistance of the power supply. Every power supply has a limit to how much current can be drawn. It is limited by the internal resistance and due to ohms law the more current drawn through a resistor, then the more voltage is produced across it. This is in opposition to the terminal voltage and is subtracted from it.

How do you find the voltage?
Using Ohm's law, you can find voltage if power is given. The equation needed to solve for power is P(Power)= Voltage(E) x Current(I). Ohm's Law describes the relationship between resistance, current, power, and voltage.
In a fixed voltage circuit where the resistance is increased voltage drops?
If the voltage is fixed, the using Ohms law: V=IxR If R increases, then the current will decrease proportionally.

How do you measure the resistance in a parallel circuit?
You have to measure the voltage, and the current. The resistance is then calculated by using Ohm's Law.
How much current flows through a 12 ohm flashlight bulb operating at 3.0 volts?
Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.
