If a 5 ohm resistor and a 10 ohm resistor are connected in series, what is the voltage across the 10 ohm resistor when a current of 2 A flows through the circuit?
Step 1: Identify the resistors in the circuit. We have a 5 ohm resistor and a 10 ohm resistor.
Step 2: Understand that the resistors are connected in series, which means the same current flows through both resistors.
Step 3: Note the current flowing through the circuit, which is given as 2 A.
Step 4: Use the formula for voltage across a resistor, which is V = I * R, where V is voltage, I is current, and R is resistance.
Step 5: Substitute the values into the formula for the 10 ohm resistor: V = 2 A * 10 ohm.
Step 6: Calculate the voltage: V = 20 V.
Step 7: Conclude that the voltage across the 10 ohm resistor is 20 V.
Ohm's Law – Ohm's Law states that the voltage (V) across a resistor is equal to the current (I) flowing through it multiplied by the resistance (R), expressed as V = I * R.
Series Circuits – In a series circuit, the same current flows through all components, and the total resistance is the sum of individual resistances.
