DETERMINING RESISTANCE IN A BASIC CIRCUIT.
Therefore, resistance equals 10 Ohms for the circuit shown in figure 5.
Using the equation below and the circuit shown in figure 6 on the following
page, we will solve for the unknown E.
o
Formula:
E=IxR
o
Given:
I = 0.5 ampere
R = 45 Ohms
o
Solution:
E = 0.5 ampere x 45 Ohms
E = 22.5 volts
Therefore, voltage equals 22.5 volts for the circuit shown in figure 6.
The Ohm's law equation and its various forms may be obtained readily, with
the aid of figure 7 on page
