Q

Hoekom sal R1 die langste wees?

A

R1 bied die grootste weerstand omdat die voltmeter wat daaroor geskakel is die grootste lesing het.
Hoe langer die resistor, hoe groter die weerstand

A

R = V/I
= 18/3
= 6 ohm

Q

Bespreek twee maniere waarop die totale stroomsterkte van die stroombaan verhoog kan word.

A

Daar kan nog selle in serie geskakel word
Die resistors kan in parallel geskakel word
Die totale weerstand sal afneem dus sal die totale stroom toeneem
