Q
Q: A circuit has a current of 3A and a resistance of 6Ω. What is the voltage across the circuit? (2019)
Solution:
Using Ohm's Law, V = I * R = 3A * 6Ω = 18V.
Steps: 5
Show Steps
Step 1: Identify the values given in the problem. We have a current (I) of 3 Amperes (A) and a resistance (R) of 6 Ohms (Ω).
Step 2: Recall Ohm's Law, which states that Voltage (V) equals Current (I) multiplied by Resistance (R). The formula is V = I * R.
Step 3: Substitute the values into the formula. Replace I with 3A and R with 6Ω. So, it becomes V = 3A * 6Ω.
Step 4: Perform the multiplication. Calculate 3 * 6, which equals 18.
Step 5: Write down the result. The voltage (V) across the circuit is 18 Volts (V).
