# Which type of circuit, series or parallel, will have a larger current passing through it if connected the same potential difference? Why?

IF the resistors all have the same value, two in series will have half the current of one resistor alone, and two in parallel will have twice the current of that one alone. so two in series will have 1/4 the current of two in parallel. Or, two in parallel will have four times the current of two in series.

IF the resistors are all the same value.

Why? ohm’s law and the laws of series and parallel resistors. Two in series have twice the resistance, thus half the current. Two in parallel have half the resistance and thus twice the current.

You are seeking a reasonable explanation to your question but you don’t have enough knowledge to understand the reasonable explanation.

Study Electronics to find the answer.

If resistances are parallel then the effective resistance will be smaller. The current will be more. Resistance will be highest when they are in series and current will be less.

Ah, it is series I think.

2 resistors R in series:

current of the circuit is

I = V / 2R

current flowing in each resistence is

I = V / 2R

2 resistors R in parallel:

overall current in the circuit is

V = 2 V / R

current flowing in each resistence is

I = V / R

Not enough information. Kind of like asking which type of car can hold more people, red cars or blue cars?

Series: two resistors of 10 ohms each, connected to 10 volt source = 1 amp current

Parallel: two resistors of 100 ohms each, connected to 10 volt source = 0.2 amp current

Another series: two resistors of 50 ohms each, connected to 10 volt source = 0.1 amp current

So you see, a series circuit can have more or less current than a parallel circuit. It depends on the resistance.
