36.Ahmed thought that these smart houses would need a lot of current. He worked out how much
current it would need to run five light bulbs. Each light bulb was 12 W and ran off the 240 V
mains. He used the following equation.
power = voltage current
How much current is needed to run five light bulbs?
A 0.05 A
B 0.025 A
C 0.25 A
D 0.5 A

security lamps.
The lamps use a current of 0.2A.
He researched some information on the internet.
The table shows some technical details about two types of rechargeable battery.
value vigour
Type NiCd NiMH
MAhr 800 2500
recharge time 5 hours 12 hours
number of times it can be recharged 1000 420
One good reason for NOT buying a value battery is
A it has no memory effect
B it recharges quite quickly
C it wont power the lamps all night
D it can be recharged 1000 times
Ahmed found more information about the vigour rechargeable battery.
The graph shows the voltage that the vigour cell produces when different currents are used.
38.Which statement about the battery is false?
Athe battery lasts longer when the load current is smaller.Bthe output voltage is greater when the current is lower.Cwhen the current is 2.5A, the output voltage is greater than 1V for more than 1 hour.

Dthe battery will need to be recharged more often when the output current is lowerElectroconvulsive therapy
Dr. Simon treats patients suffering from depression and is considering using ECT for one of his
patients. Doctors are still not sure how ECT works, but they have found that it can help some
people to get better.
39.Here are two statements about this.
1 Get the patients consent in writing
2 Give the patient a copy of the official guidance
Which of these must Dr. Simon do before he can treat the patient with ECT?
A 1 only
B 2 only
C both 1 and 2D neither
40. The shocking circuit connected to the patient includes a 1A fuse and a residual current circuit
breaker (RCCB). The pulses of current only last for 1.5 milli seconds.
Here are two statements about this.
1 Residual current circuit breakers are designed to act more quickly then fuses but cannot
completely present a shock.
2 If the shocking current exceeded 1 A, the fuse might not blow because the current exists
for such a short time.
Which of the statements is correct?
A 1 only
B 2 only
C both 1 and 2
D neither
