Question: If a circuit has a voltage of 30V and a total resistance of 10Ω, what is the total current flowing through the circuit?

Options:

Correct Answer: 4A

Solution:

Using Ohm\'s law, I = V/R = 30V/10Ω = 3A.

If a circuit has a voltage of 30V and a total resistance of 10Ω, what is the total current flowing through the circuit?

If a circuit has a voltage of 30V and a total resistance of 10Ω, what is the total current flowing through the circuit?

Step 1: Identify the voltage in the circuit, which is given as 30V.
Step 2: Identify the total resistance in the circuit, which is given as 10Ω.
Step 3: Recall Ohm's law, which states that current (I) is equal to voltage (V) divided by resistance (R).
Step 4: Write the formula for current: I = V / R.
Step 5: Substitute the values into the formula: I = 30V / 10Ω.
Step 6: Calculate the current: 30 divided by 10 equals 3.
Step 7: Conclude that the total current flowing through the circuit is 3A.

Ohm's Law – Ohm's Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor.
