Question

Two electric circuits 1 and 2 are shown below

Answer 1

1) frst circuit has more resistance

2)second circuit

3)im not sure bt i think in second circuit

Answer 2

Answer:

1) a ( R in series is directly added)

2) b ( lower resistance = more current ) (ohm's law)

3) b (uk right)

4) b (coz h=i²rt) ( a has more resistance , but uk if resistance decreases the value of current will increase

in square h=i²rt )
