Question: If the voltage across a resistor is 240V and the resistance is 60 ohms, what is the current flowing through it? (2020)
Options:
2A
4A
6A
8A
Correct Answer: 6A
Solution:
I = V / R = 240V / 60Ω = 4A.

Questions & Step-by-Step Solutions
If the voltage across a resistor is 240V and the resistance is 60 ohms, what is the current flowing through it? (2020)
Step 1: Identify the voltage across the resistor. In this case, it is 240 volts (V).
Step 2: Identify the resistance of the resistor. Here, it is 60 ohms (Ω).
Step 3: Use the formula for current (I), which is I = V / R.
Step 4: Substitute the values into the formula: I = 240V / 60Ω.
Step 5: Calculate the result: 240 divided by 60 equals 4.
Step 6: Conclude that the current flowing through the resistor is 4 amperes (A).
Ohm's Law – Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor.
