Problema Solution
Electrical Current: The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 1/3 amperes when the resistance is 1620 ohms. What is the current when the resistance is 4500 ohms?
Answer provided by our tutors
by using Ohm's law
Voltage = Current * Resistance
V = I * R
1) V = 0.333 * 2268 = 755 volt
2) I = V / R
I = 755 / 12348 = 0.061 A
= 61 mA
