(C) Current (D) Power

2. Total current drawn from four 1.5V cells connected in series is 1 ampere. Each cell supplies:
(A) 1 ampere (B) 0.25 ampere
(C) 1.5 amperes (D) 4 amperes

3. A 100 ohm 2 resistor is to be used in a circuit carrying a current of 0.5 A. Its power rating should be watt:
(A) 50 (B) 25
(C) 200 (D) 500

4. A Silicon Solar Cell is basically a:
(A) Photo conductive cell (B) Photo voltaic cell
(C) Photo emissive cell (D) of these

5. In a centre tap full—wave rectifier, Vm is the peak voltage between the Centre tap and one end of the secondary. The maximum voltage across the reverse biased diode is
(A) Vm
(B) ½ Vm
(C) 2 Vm (D) None of these

6. The combained resistance of two equal resistors connected in parallel is equal to:
(A) ½ the resistance of one resistor
(B) twice the resistance of one resistor
(C) the resistance of one resistor divided by the other
(D) ¼ the resistance of one resistor

7. The superposition theorem is essentially based on the concept of:
(A) Duality (B) Linearity
(C) Reciprocity (D) Non—Linearity
