Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.A heating element has resistance 100 ohm at 27.0 C and 117 ohm at the working temperature. With alpha = 1.70 x 10^-4 /C, the working temperature is about:
- A.1027 C
- B.117 C
- C.827 C
- D.570 C
-
2.Two resistors R and 2R are connected in series across a battery. The ratio of heat dissipated in R to that in 2R is:
- A.1 : 2
- B.2 : 1
- C.1 : 4
- D.4 : 1
-
3.A cell of emf e and internal resistance r delivers maximum power to an external resistance R when:
- A.R = r
- B.R = 0
- C.R is infinite
- D.R = 2r
-
4.Assertion (A): While a battery is being charged, its terminal voltage exceeds its emf. Reason (R): During charging the current is forced into the positive terminal, so the terminal voltage equals e + Ir.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
5.Assertion (A): A series resistor is used in a battery charging circuit. Reason (R): The series resistor limits the charging current to a safe value.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
