The potential difference across the 300 ohm resistor is
6 V
9 V
2 V
30 V
In parallel circuits potential difference across the whole circuit is equal to sum of potential difference across each component
true
False because in parallel circuit P.D across each component is equal to the P.D across the whole circuit
In a parallel circuit the current flowing into or out of the parallel branches is equal to the sum of the individual current in each of the parallel branches.
false
true
What happens to other bulbs if one of the bulbs blows?
they will glow brighter
