Question

d) Find the equivalent resistance if -
i. two resistors of two ohm and three ohm connect in series with 6v battery ​

Answer 1

Explanation:

For the above circuit the easiest way to find the total current from the battery is:

I(current R1)= E(voltage R1)/R1(3 ohm)= 6V/3 ohm= 2A (amps)

I(current R2)= E(voltage R2)/R2(2 ohm)= 6v/2 ohm= 3A (amps)

I(total current)= I(current R1) + I(current R2)= 2A + 3A= 5A

This is all done by Ohms Law: E=IR or I= E/R or R=E/I

The voltage in a parallel circuit is the same across all resisters and is the supply E

The total current of E(supply) is equal to the sum of the branches of current:

I(total)= I1 + I2 by Kirchhoff Current Law

Answer 2

Answer:

the voltage in the parallel circuit is the same across all resistors and is the supply E
