Ohms Law.

A. What power is dissipated when a ½ amp current flows through a 5 ohm resistor?
I=V/R=.25 .5-.25=.25

B. What current is flowing in the 8 ohm resistor?
The 8 volt
The circuit flows clockwise the first resistor is a 2 ohm the second is an 8 ohm circuit in a split circuit.

E=I*R .5/8=.1562

C. What is the current flowing through the 4 ohm resistor?
The resistor is in parallel. Find the value of the total current flowing into a parallel circuit.
1.25/5=.25
