How many 176 ohm resistors ( in parallel) are required to carry 5A on a 220V line?
Asked by adalroshan2464 | 28th Mar, 2019, 02:37: PM
let us assume there is n number of resistor required. since all the resistors are connected in parallel connection so the equivalence resistance = R = 176/n Ω
Using ohms law
220 = 5×(176/n)
n = (176×5)/220
n = 880/220 = 4
So the number of resistor would be 4

- If the resistance is doubled then the length also doubled but your in your MCQ quiz the but the length is l/2
- explain ohms law
- To find rarional btw potential difference and current
- A resistance wire made from German silver has a resistance of 4.25 ohm. Calculate the resistance oi another wire, made from the same material such that its length increased by 4times and area decreased by 3times.
- define ohms law
- Please find the attached question,
- Why resistance will increase to 3 times when length is increased 3 times and will not increase to 9 times?
- A battery of 9V is connected in series with resistors of 0.2 ,0.3, 0.4, 0.5, and 12 . How much current would flow through the 12 resistor?
- A bulb is rated as 60W , 220V . what does it mean?
