Q
Q: If a circuit has a total resistance of 12 ohms and a current of 3A flows through it, what is the voltage across the circuit?
Solution:
Using Ohm's law, V = I * R = 3A * 12 ohms = 36V.
Steps: 5
Show Steps
Step 1: Identify the values given in the problem. We have a total resistance (R) of 12 ohms and a current (I) of 3A.
Step 2: Recall Ohm's law, which states that Voltage (V) = Current (I) * Resistance (R).
Step 3: Substitute the values into the formula: V = 3A * 12 ohms.
Step 4: Calculate the result: 3 * 12 = 36.
Step 5: Conclude that the voltage across the circuit is 36 volts.
