Exit ticket: A lamp is plugged into a 110 Volt electrical outlet. There is a 9 Watt LED bulb in the lamp. a. What is the current in the bulb? b. What is the resistance of the bulb?

(a) 0.081 A (b) 1358.02 ohms

Explanation:

Voltage, V = 110 volt

Power of a LED bulb, P = 9 Watt

(a) Let the current is I. The formula for ower in terms of voltage and power is given by :

P = VI

(b) Let R is the resistance of the bulb. Using Ohm's law as follows :

V = IR

Hence, this is the required solution.
