Question 5
5(either)(a)[2]
(t =) Q / I or 7.2 / 0.0016 or 7.2 / 1.6 or 4.5 × 10N 4500 s
5(either)(b)(i)[1]
does not change and p.d. / voltage across resistor N does not change / ammeter 2 is not in the branch that contains the LDR
5(either)(b)(ii)[2]
resistance of LDR increases or current (in M / in ammeter 1) decreases time taken increases
5(or)(a)[1]
(bipolar npn) transistor
5(or)(b)(i)[1]
its resistance decreases or current in the LDR increases
5(or)(b)(ii)[3]
base current or base-emitter voltage increases there is now a current in the relay coil or transistor switches (circuit) on or coil / core magnetised relay coil attracts the relay switch / closes switch (in the mains circuit)
