Question

a circuit has 12 volts, and 4 ohms of resistance. what is the amperage according to the ohms law calculation?
select one:
○ a. 12 amps
○ b. 8 amps
○ c. 3 amps
○ d. 48 amp

Explanation:

Step1: Recall Ohm's Law

Ohm's Law is given by \( I = \frac{V}{R} \), where \( I \) is the current (amperage) in amps, \( V \) is the voltage in volts, and \( R \) is the resistance in ohms.

Step2: Identify given values

We are given \( V = 12 \) volts and \( R = 4 \) ohms.

Step3: Calculate the current

Substitute the given values into the formula: \( I=\frac{12}{4} = 3 \) amps.

Answer:

c. 3 amps
