A technician is checking a circuit with excessive resistance. The current flow through the circuit should be 10 amps, but a check with an ammeter measures only 6 amps. The technician measures a voltage drop of 1.0 volts across the switch terminals when the circuit is turned on. What is the resistance of the switch?
A)1/60 ohm
B)1/6 ohm
C)6 ohms
D)60 ohms

Question

Quizplus · Accepted Answer

The resistance of the switch can be calculated using Ohm's Law, which states that resistance (R) equals voltage (V) divided by current (I). Given a voltage drop of 1.0 volts and a current of 6 amps, the resistance is R = V/I = 1.0V / 6A = 1/6 ohm.
