Question

how are the two resistor of resistance r2 are the connected to a battery of three volt to obtain maximum current work out current​

Answer 1

Explanation:

To obtain maximum current ,we will arrange the two given resistors in parallel .Only then,the equivalent resistance will be minimum and current maximum. R(eq)=R1*R2/(R1+R2) Therefore,V=I*R(eq) gives maximum current. (b)3bulb of 100 w for 5 hrs. 3 ×100×5 = 1500 w = 3/2 kwh 2 fans of 50 watt each used for 10 hours daily. 2 × 50 × 10 = 1000 w = 1 kwh. an electric heater of 1.00 kW is used for half an hour daily 1 kwh × 1/2 hr = 1/2 kwh. for 31 days. 3/2 × 31 = 93/2 1 × 31 = 31 1/2 × 31 = 31 / 2. now adding these 93/2 + 31/2 + 62/2 = 196/2. = 98. now cost is 98 × 3.6 = Rs. 352.8
