Here are the solutions to the problems: 1. Basic Current Calculation Step 1: Identify the given values. Voltage V = 9 V Resistance R = 3 Step 2: Use Ohm's Law to find the current I. I = (V)/(R) Step 3: Substitute the values and calculate. I = 9 V3 I = 3 A The current flowing through the circuit is 3 A. 2. Resistance Determination Step 1: Identify the given values. Current I = 0.5 A Voltage V = 120 V Step 2: Use Ohm's Law to find the resistance R. R = (V)/(I) Step 3: Substitute the values and calculate. R = 120 V0.5 A R = 240 The resistance of the bulb is 240 . 3. Voltage Calculation Step 1: Identify the given values. Resistance R = 15 Current I = 2 A Step 2: Use Ohm's Law to find the voltage V. V = IR Step 3: Substitute the values and calculate. V = (2 A)(15 ) V = 30 V The voltage across the resistor is 30 V.
