How do you find the resistance?
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.
How many 176 resistors in parallel are required to carry 5 A on a 220 V line?
Q 10: How many 176 Ω resistors (in parallel) are required to carry 5 A on a 220 V line? From Ohm’s law, ∴four resistors of 176 Ω are required to draw the given amount of current.
When three equal resistance are connected in parallel the effective resistance is 1 by 3 home if all are connected in series the effective resistance is?
The effective resistance of three equal resistances, each of resistance r, connected in parallel, is. Then 1R=1r+1r+1r=3r.
