Ohm's Law Study Guide with complete solution
Kaya collects the data shown in the table.
What is the resistance in the circuit?
20 Ω
How are the current and resistance related when the voltage of a circuit is
constant?
The current is cut in half when the resistance doubles because they are inversely
proportional.
Jaipal measures a circuit at 1.2 A and 24 Ω . Using Ohm's law, what can he
calculate for the circuit?
voltage (V)
What is the resistance of a light bulb if a potential difference of 120 V will produce
a current of 0.5 A in the bulb?
240Ω
When the resistance in a circuit remains constant, how are the voltage and
current related?
The current doubles when the voltage doubles because they are directly proportional.
To increase the current in a circuit, the _______can be increased.
voltage
Which statement describes the relationship of voltage and current?
NOT
Voltage is directly proportional to current because I=VR.
Aretha measures a circuit at 110 V and 240Ω . Using Ohm's law, what can she
calculate for the circuit?
current
Ohm's law describes the relationship between which quantities?
current, voltage, and resistance
A circuit has a current of 2.4 A. The voltage is increased to 4 times its original
value, while the resistance stays the same.
How should the resistance change to return the current to its original value if the
voltage remains at its increased amount?
It should increase to four times its value.
