Question: In a DC circuit, if the voltage across a 10Ω resistor is 20V, what is the current through the resistor?

Options:

Correct Answer: 2A

Solution:

Using Ohm\'s Law, I = V/R = 20V / 10Ω = 2A.

In a DC circuit, if the voltage across a 10Ω resistor is 20V, what is the current through the resistor?

In a DC circuit, if the voltage across a 10Ω resistor is 20V, what is the current through the resistor?

Step 1: Identify the values given in the problem. We have a voltage (V) of 20 volts and a resistance (R) of 10 ohms.
Step 2: Recall Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). The formula is I = V / R.
Step 3: Substitute the values into the formula. Replace V with 20V and R with 10Ω: I = 20V / 10Ω.
Step 4: Perform the division. Calculate 20 divided by 10, which equals 2.
Step 5: State the result. The current (I) through the resistor is 2 amperes (A).

Ohm's Law – Ohm's Law states that the current (I) 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, expressed as I = V/R.
