1. There is a circuit with an emf source of 6.0V connected to a lamp and a current flow of 2.0A.
Assuming that the wires connecting the whole circuit is resistance free, what is the resistence of the lamp?

Explanation

V=IR
R=V/I
R=6.0/2.0
R=3.0Ω

What is the total current of the circuit?

Explanation

I=VR
Total current= total of 3 currents for each branch of a parallel circuit
total current= 12/2 + 12/3 +12/6
= 12.0A

Submit
3.
What is the effective resistance of the circuit?

Explanation

1/total resistance (parallel)= 1/r + 1/r + 1/r (r being the respective resistance)
in this case
1/effective resistance= 1/6 + 1/3 + 1/2
effective resistance = 1Ω

Submit
4. What is the maximum possible voltage and current through the circuit?

Explanation

I=V/R
=6/25
=0.24A
v=IR
=0.24X25
=6.0V

Submit
5.
What is the P.D of each resistor?

Explanation

P.d(1)=(24/[24+48])12
=4V

P.d(2)=(48/[24+48])12
=8V
