Explanations for Science Students||Already Graded A+
1. What is the SI unit of electric charge?
A. Volt
B. Coulomb
C. Ampere
D. Ohm
Answer: B. Coulomb
The coulomb (C) is the SI unit of electric charge and represents the amount of
charge transported by a current of one ampere in one second.
2. Ohm’s Law is expressed as:
A. P = VI
B. V = IR
C. I = PR
D. R = VI
Answer: B. V = IR
Ohm’s Law relates voltage (V), current (I), and resistance (R) in a linear circuit.
3. A resistor with a resistance of 10 Ω carries a current of 2 A. What is the
voltage across it?
A. 5 V
B. 10 V
C. 20 V
D. 40 V
Answer: C. 20 V
Using V = IR → V = 2 A × 10 Ω = 20 V.
4. Which component stores energy in an electric field?
,A. Inductor
B. Resistor
C. Capacitor
D. Transformer
Answer: C. Capacitor
A capacitor stores electrical energy in an electric field between its plates.
5. Which component stores energy in a magnetic field?
A. Capacitor
B. Inductor
C. Diode
D. Transistor
Answer: B. Inductor
An inductor stores energy in a magnetic field created by current flowing
through it.
6. The unit of inductance is:
A. Farad
B. Ohm
C. Henry

Answer: D. Current
Current is constant throughout a series circuit.
, 8. In a parallel circuit, which quantity is the same across all branches?
A. Current
B. Voltage
C. Resistance
D. Power
Answer: B. Voltage
Each branch in a parallel circuit has the same voltage.
9. The equivalent resistance of two equal resistors R in series is:
A. R
B. R/2
