Q: In a circuit, if the voltage is tripled and the resistance remains constant, what happens to the current? (2022)
Solution:
According to Ohm's law, if V is tripled, I will also triple.
Steps: 7
Show Steps
Step 1: Understand Ohm's Law, which states that Voltage (V) = Current (I) x Resistance (R).
Step 2: Identify that in this scenario, the resistance (R) remains constant.
Step 3: Note that if the voltage (V) is tripled, we can express this as V' = 3V, where V' is the new voltage.
Step 4: Since R is constant, we can rearrange Ohm's Law to find the current: I = V / R.
Step 5: Substitute the new voltage into the equation: I' = V' / R = (3V) / R.
Step 6: Simplify the equation: I' = 3(V / R) = 3I, where I' is the new current.
Step 7: Conclude that if the voltage is tripled, the current will also triple.
