The key formula ===> Voltage = (current) x (resistance)
Plug in the numbers given ===> Voltage = (3.6 A) x (5.0 ohms)
Dooda multiplication ===> Voltage = 18 volts
Answer: The correct answer is 18 V.
Explanation:
The mathematical expression from Ohm's law is as follows:
V=IR
Here, V is the voltage, R is the resistance and I is the current.
It is given in the problem that A circuit has a current of 3.6 A and a resistance of 5.0 Ω.
Put R= 5 ohm and I= 3.6 A in the above expression.
V= (3.6)(5)
V=18 V.
Therefore, the value of voltage is 18 V.
