What is the current flow through R1, R2, and R3?
Answer: Option
Explanation:
V = IR
V = I(R1 + R2 + R3)
I = V/(R1 + R2 + R3)
= 9/(3 + 3 + 3)
= 9/9
= 1 Amp.

The current is 1 amp, In all series resistors which are 3+3+3=9.
So, 9/9=1 amp
So, 9/9=1 amp

I = V/R.
V = 9V; R = 3+3+3.
= 9.
V = 9; R = 9.
I = V/R.
I = 9/9.
I = 1 Amp.
V = 9V; R = 3+3+3.
= 9.
V = 9; R = 9.
I = V/R.
I = 9/9.
I = 1 Amp.

The total resistance of the circuit is 9 ohm, so by ohm law I= Vs/Rt.
9v/9ohm = 1amp.
9v/9ohm = 1amp.

The answer is A because Rs. 9 and the voltage is 9 so we use I = V/R and then you will get your answer.

The effective resistance in the circuit is 9 ohms and the emf is 9volts. By Ohm's law, I=V/R =9/9=1 A. Since components are in series with the voltage source the same current of 1A flow through them.

I = V/R.
If V = 9V; R = R1+R2+R3.
= 3+3+3.
= 9.
V = 9; R = 9.
I = V/R.
I = 9/9.
I = 1 Amp.
If V = 9V; R = R1+R2+R3.
= 3+3+3.
= 9.
V = 9; R = 9.
I = V/R.
I = 9/9.
I = 1 Amp.

Yes, in fact, series resistors vary only the voltage, but not the current, whilst, if the resistors were placed in parallel among each other, the current will change and the voltage will remain unchanged.

Yes its correct because resistors are in series thats why same current will flow.

Current will be same across 3 resistor as they connected in series.

Same current flows in series ckt.
