V
Q1. Is the circuit below a series or parallel
Q2. If the reading on Ammeter A is 2AWhat will the reading on A2 and A3 be?
A
A3
A2
Q1. Is the circuit below a series or parallel
Q2. If the reading on Ammeter 4 is 2A what
will the reading on:
A2, A3 and A1 be?
A1
A4
A2
A3
Q1. Is the circuit below a series or parallel
Q2. If the reading on Voltmeter 1 is 8V what
will the readings on
V2 and V3 be?
V1
NB Voltmeters are
connected in parallel
V2
V3
• For a series circuit, the sum of the voltages for each component is
equal to the voltage across the cell or battery.
•
V1 = V2 + V3
Q1. Is the circuit below a series or parallel
Q2. If the reading on Voltmeter 1 is 8V what
will the readings on
V2 and V3 be?
V1
V2
V3
• For a parallel circuit, the voltage across the cell/battery is the same
as the voltage across each branch.
• V1 = V2 = V3
