Questions & Step-by-Step Solutions
In a circuit with a 5V battery and two resistors in parallel (5Ω and 10Ω), what is the current through the 10Ω resistor?
Step 1: Identify the voltage of the battery, which is 5V.
Step 2: Identify the resistance of the resistor we are interested in, which is 10Ω.
Step 3: Use Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R).
Step 4: Plug in the values into the formula: I = V / R.
Step 5: Substitute the values: I = 5V / 10Ω.
Step 6: Calculate the current: I = 0.5A.
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.
Parallel Resistors – In a parallel circuit, the voltage across each resistor is the same, and the total current is the sum of the currents through each resistor.
