Question

A 12 volt battery is connected to a circuit having 3 series connected resistor having resistance of 4 ohm 9 ohm and 11 ohm determine the current flowing through the p.d across the 9 ohm resistor

Answer 1

EXPLANATION:

Explanation:

V = 12 Volts

R = 9 Ohm

I = ?

V=IR

12=9I

I = 12/9

I = 1.3 Ampere

Answer 2

Answer:

The correct answer is 0.5A.

Explanation:

Total resistance is series is: R(total)-R1+R2+R3

=(4+9+11)ohm

=24ohm

Also potential difference.V=12V

From ohms law

V=IR

=V/R

-12/24

=0.5A

Two or more resistors are said to be connected in series when the same amount of current flows through all the resistors. In such circuits, the voltage across each resistor is different. In a series connection, if any resistor is broken or a fault occurs, then the entire circuit is turned off. The construction of a series circuit is simpler compared to a parallel circuit. Rtotal = R1+ R2+.....+ Rn

The total resistance of the system is just the total sum of individual resistances.
