Since any limit is not mensioned on the potential difference accross the circuit,
we can assume that whatever be the circuit is each of them will have max. current, I. Since max. power is P=18W
nd each resistance is R=2 ohm
So that,

The maximum current that can flow through a circuit with resistors in parallel can be determined by analyzing the power rating and resistance values of the components. In this case, we have two resistors with equal resistance values of 2 ohms.
Understanding Power and Resistance
- Each resistor can withstand a maximum power of 18W.
- The power dissipated by a resistor is calculated using the formula: P = I^2 * R, where P is power, I is current, and R is resistance.
Calculating Maximum Current for One Resistor
- Rearranging the formula for current gives us: I = sqrt(P/R).
- Substituting the values for one resistor:
- P = 18W
- R = 2 ohms
- Thus, I = sqrt(18W / 2 ohms) = sqrt(9) = 3A.
Finding Total Current in Parallel Configuration
- In a parallel circuit, the total current is the sum of the currents through each resistor.
- Since both resistors are identical and can each carry a maximum of 3A, the total maximum current is:
- Total Current = I1 + I2 = 3A + 3A = 6A.
Conclusion
- The maximum current that can flow through the circuit with two 2-ohm resistors in parallel, each capable of dissipating 18W, is 6A.
- Always ensure that the total current does not exceed the maximum power rating of the resistors to prevent overheating and failure.
