1Electric current is measured in which SI unit?
A.Volt (V)
B.Ampere (A)
C.Ohm (Ω)
D.Coulomb (C)
Explanation: The SI unit of electric current is the ampere (A). One ampere equals one coulomb of charge passing a point per second.
2A 6 Ω resistor carries a steady current of 3 A. The voltage across it is:
A.2 V
B.9 V
C.18 V
D.0.5 V
Explanation: Ohm's law: V = IR = 3 A × 6 Ω = 18 V.
3Potential difference is defined as the work done in moving a unit positive charge from one point to another. Its SI unit is the:
A.Ampere
B.Joule
C.Volt
D.Watt
Explanation: One volt is one joule per coulomb of charge moved. V = W/Q in SI base relations.
4The resistance of a conductor at constant temperature is 20 Ω. If the current is 0.5 A, the power dissipated is:
A.5 W
B.10 W
C.40 W
D.0.025 W
Explanation: P = I²R = (0.5)² × 20 = 0.25 × 20 = 5 W. Also P = VI with V = IR = 10 V gives 10×0.5 = 5 W.
5Three resistors of 2 Ω, 3 Ω and 5 Ω are connected in series. The equivalent resistance is:
A.0.97 Ω
B.3.33 Ω
C.10 Ω
D.30 Ω
Explanation: Series resistances add: R_eq = 2 + 3 + 5 = 10 Ω.
6Two 8 Ω resistors are connected in parallel. The equivalent resistance is:
A.16 Ω
B.8 Ω
C.4 Ω
D.2 Ω
Explanation: For two equal resistors R in parallel, R_eq = R/2 = 8/2 = 4 Ω. Also 1/R_eq = 1/8 + 1/8 = 1/4.
7A 100 W lamp is operated continuously for 10 hours. Energy consumed is:
A.1 kWh
B.10 kWh
C.100 kWh
D.0.1 kWh
Explanation: E = P × t = 100 W × 10 h = 1000 Wh = 1 kWh (since 1 kWh = 1000 Wh).
8Which statement correctly states Ohm's law for a metallic conductor at constant temperature?
A.V is proportional to I; V = IR
B.V is inversely proportional to I
C.R is proportional to I at fixed V only by definition of power
D.I is independent of V
Explanation: Ohm's law: the potential difference V across an ohmic conductor is proportional to current I, with V = IR at constant temperature.
9Four 12 Ω resistors are connected in parallel. The equivalent resistance is:
A.48 Ω
B.12 Ω
C.6 Ω
D.3 Ω
Explanation: For n equal resistors R in parallel, R_eq = R/n = 12/4 = 3 Ω.
10A wire has resistance 10 Ω. If both its length and cross-sectional area are doubled (same material, same temperature), the new resistance is:
A.10 Ω
B.5 Ω
C.20 Ω
D.40 Ω
Explanation: R = ρL/A. If L → 2L and A → 2A, R' = ρ(2L)/(2A) = ρL/A = R = 10 Ω.
