When 60 resistance each of 60 ohm are connected in parallel their equivalent resistance will be?

Hence, the equivalent resistance is 36 ohms.

What is the equivalent resistance of a 40 ohm and a 60 ohm resistor connected in parallel?

The equivalent resistance of parallel combination of 60 ohms & 40ohms is 24Ohm.

What ohm resistor do I need?

A rule of thumb is to find a resistor with twice the power rating. Here I would choose a 250 mW resistor since those are the most standard ones. Usually, you can just use the cheapest resistor you can find with the correct power rating.

How do I choose a resistor?

Resistor selection requires three steps:

1. Determine the resistance and the watts to be dissipated by the resistor.
2. Determine the proper “Watt Size” (physical size) as controlled by watts, volts, permissible temperatures, mounting conditions and circuit conditions.

Does size of resistor matter?

Generally speaking the larger their physical size the higher its wattage rating. However, it is always better to select a particular size resistor that is capable of dissipating two or more times the calculated power.

What happens to the effective resistance if 3 resistance each of 60 ohm are connected in parallel?

The effective resistance of three resistors connected in parallel is 60/47 Ω. When one wire breaks, the effective resistance becomes 15/8 ohms.

What is the equivalent resistance in a parallel circuit?

If the two resistances or impedances in parallel are equal and of the same value, then the total or equivalent resistance, RT is equal to half the value of one resistor. That is equal to R/2 and for three equal resistors in parallel, R/3, etc.

How do you find the equivalent resistance in A and B?

∵6Ω and 3Ω are in parallel.

1. So, their equivalent Resistance R′=6Ω+3Ω6Ω×3Ω
2. So, this equivalent Resistance R′′=4Ω+12Ω4Ω×12Ω
3. R′′=1648Ω=3Ω

How do I know what wattage resistor to buy?
