Study the problem below, then continue.
100 mV = 20 ______ A
5k Ω
Solution:
Substitute equivalent powers of 10 for m and k; fill in the blank with the proper
power of 10; then substitute a metric prefix for equivalent power of 10.
Thus:
100 mV = 100 X 10-3 V = 20 X 10-6 A= 20 A
5k Ω
5 X 103 Ω
NOTE:
This is a practical electrical problem working with Ohm's law:
volts (V) = amperes (A)
ohms (Ω)
