Question

The voltage drop in a circuit of known resistance is dependent on

A. The voltage of the circuit
B. Only the resistance of the conductor and does not changed with a change in either voltage or amperage
C. The amperage of the circuit

Answer 1

According to Ohm's law, the voltage drop across a resistor is calculated using V = IR, where I is the current and R is the resistance.

Step-by-step explanation:

According to Ohm's law, the voltage drop, V, across a resistor when a current flows through it is calculated using the equation V = IR, where I equals the current in amps (A) and R is the resistance in ohms (Ω). Another way to think of this is that V is the voltage necessary to make a current I flow through a resistance R.
