Circuits/Voltage Question?

Question

I have a 3.0 V power source and bulbs set up in series, parallel, and series/parallel circuits.

Will the voltage across each resistor be the same or different if the resistors are in a:
a) series circuit
b) series/parallel circuit
c) parallel circuit

Answer 1

c

Answer 2

It will be C. Parallel Circut.
Always keep this in mind as second nature as breathing:

Voltage is the same across a parallel circuit>
Current is the same in a series circuit.>

In a parallel circuit voltage is the same across all the compents, but current varies through each component depending on the component's resistance or reactance.

In a series circuit current flowing through the components in the same but the voltage drops across the components vary depending on the component's resistance or reactance.

Answer 3

a) 3 Volts divided by the number of bulbs

b) circuit not defined

c) 3 volts across all of them

note you did not say how many bulbs

note also the question started with bulbs and then used the term resistors

very careless question

In a) all the components will see the same current
so if they are identical .... same voltage

In C) they all see the same voltage
and if identical, the same current

Only in B) will the currents and voltages be different
