Sample NECO SSCE Physics 2007 questions

1. A charge of 24 C passes a point in a circuit in 6 s. What is the current?
  1. 4 A
  2. 0.25 A
  3. 18 A
  4. 144 A

Answer: A. 4 A

Current is charge divided by time, so I = 24/6 = 4 A.

2. Two resistors of 6 ohms and 3 ohms are connected in parallel. What is their equivalent resistance?
  1. 9 ohms
  2. 2 ohms
  3. 3 ohms
  4. 18 ohms

Answer: B. 2 ohms

For parallel resistors, 1/R = 1/6 + 1/3 = 1/2, giving R = 2 ohms.

3. A device operates at 12 V and draws a current of 2 A. What is its power?
  1. 6 W
  2. 10 W
  3. 24 W
  4. 48 W

Answer: C. 24 W

Electrical power is P = VI = 12 x 2 = 24 W.

4. According to Faraday's law, which change generally increases the induced e.m.f. in a coil?
  1. The coil's electrical resistance
  2. The coil's mass
  3. The wire's length only
  4. The rate at which magnetic flux changes

Answer: D. The rate at which magnetic flux changes

Faraday's law states that induced e.m.f. is proportional to the rate of change of magnetic flux linkage.

5. An ideal transformer has 1100 turns on its primary coil and 100 turns on its secondary coil. If the primary voltage is 220 V, what is the secondary voltage?
  1. 20 V
  2. 200 V
  3. 2200 V
  4. 2420 V

Answer: A. 20 V

For an ideal transformer Vs/Vp = Ns/Np, so Vs = 220 x 100/1100 = 20 V.
