Question. 16. when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device? a. 243 a b. 27 ω c. 243 ω d. 40.5 a

Resistance = (voltage) / (current)

Resistance = (81 volts) / (3 Amperes)

Resistance = (81/3) ohms

Resistance = 27 ohms

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
