The current through a 10-ohm resistor connected to a 120-V power supply is
A)1 A.
B)10 A.
C)12 A.
D)120 A.
E)none of the above

Question

Quizplus · Accepted Answer

We can use Ohm's Law to calculate the current through the resistor:
I = V/R
where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms.

Substituting the given values, we get:
I = 120 V/10 Ω
I = 12 A

Therefore, the current through the resistor is 12 A.
