If a circuit has a total resistance of 12Ω and a current of 4A, what is the volt

If a circuit has a total resistance of 12Ω and a current of 4A, what is the voltage across the circuit? (2023)

If a circuit has a total resistance of 12Ω and a current of 4A, what is the voltage across the circuit? (2023)

Step 1: Identify the formula you need to use. The formula is Ohm's law, which states V = I * R.
Step 2: Identify the values given in the question. The current (I) is 4A and the resistance (R) is 12Ω.
Step 3: Substitute the values into the formula. Replace I with 4A and R with 12Ω in the formula V = I * R.
Step 4: Calculate the voltage. Multiply 4A by 12Ω to get V = 4 * 12.
Step 5: Perform the multiplication. 4 * 12 equals 48.
Step 6: State the final answer. The voltage across the circuit is 48V.

Ohm's Law – Ohm's Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it and the resistance (R) of the conductor, expressed as V = IR.
