If a voltage of 220 V is applied to a resistor of 20 Ω, then the amount of electric current in the circuit will be
Correct answer: A. 11 A
- A. 11 A
- B. 110 A
- C. 200 A
- D. 240 A
Explanation
To determine the current in the circuit, we apply Ohm's Law, which states that I = V/R, where I is the current in amperes (A), V is the voltage in volts (V), and R is the resistance in ohms (Ω). Given a voltage (V) of 220 V and a resistance (R) of 20 Ω, the current (I) is calculated as follows:I = 220 V / 20 Ω = 11 A.Thus, the correct answer is 11 A. The other options are incorrect because they are either based on incorrect calculations or misunderstandings of Ohm's Law.

About Steady Current
Steady current is the continuous flow of charge at a constant rate through a conductor. The topic covers current, charge, potential difference, resistance, Ohm's law, resistivity and electrical power, along with series and parallel circuits, while distinguishing conventional current direction from electron motion.
