Hydropower is a method of generating electricity that uses moving water (kinetic energy) to produce electricity. In large-scale hydropower plants the moving water drives large water turbines, and dams are needed to store water in lakes, reservoirs and rivers for later release.

Answers

I'll give you the formula to calculate the net resistance of multiple resistors I'm in parallel.

1/R = 1/R1 + 1/R2 +1/R3 +……+1/Rn.

Take the reciprocal of each resistor value and add them up. The reciprocal value of a resistor is called its admittance. Add them up to get the total admittance. Notice that this value is 1/R. So take the reciprocal by dividing 1 by the total admittance value. Then you have the net resistance for all the parallel resistors.

Now you know the total resistance of the parallel values, if there are any other resistors in series with this, add them on to get the total resistance in the circuit.

Now use Ohm's law to find the current.

I =V/R

1. paralel resistance

1/(1/10+1/15+1/30)= 30/6=5 Ohms

2. total current : V/R=24/5= 4.8A
