What is the current in Amps going through the 2nd object in a circuit where two objects are in PARALLEL, with a total power of 200W and the 1st object using 80W and the 2nd object having a Voltage of 6 Volts?
The current in amps going through the second object is 20 Amps. Given that the total power is 200W and the first object uses 80W, the second object must be using 120W. In a parallel circuit, the total power is the sum of the power of each object. Using Watts's law (P = IV), for the second object, I = P/V = 120/6 = 20 Amps.
Understanding Parallel Circuits and Current Calculation
Parallel Circuit:
A parallel circuit is a circuit that has more than one path for current flow. In such circuits, the total resistance is less than the smallest individual resistance. The voltage across each object in parallel is the same while the current flowing through each object can be different.
Ohm's Law in Action:
In Ohm's law (V = IR), the current flowing through an object is directly proportional to the voltage across it and inversely proportional to the resistance. By applying Ohm's law and Watts's law, we can easily calculate the current flowing through each object in a parallel circuit.
Calculating Current:
For the first object using 80W: I = P/V = 80/V
For the second object using 120W: I = P/V = 120/6 = 20 Amps
Therefore, the current in amps going through the second object is indeed 20 Amps.
By understanding the principles of parallel circuits and the application of Ohm's law, we can effectively analyze and calculate the current flow in complex circuit configurations.
