Question

An electric bulb is rated 100w-200v.calculate the resistance

Answer 1

plzzz mark me brainlist.........buddy :-)

Answer 2

• Answer :it's known that power is the product I.e p=4

Explanation:

V=ir(ohms law) . Since we have been value as 200 and power is 100w......

Substituting the same in p=iv and modifying the equation to calculate resistance, we get

R=v*v/p=200*200/100=400ohms

✔️✔️✔️✔️Hence, your Answer is 400ohms✔️✔️✔️✔️
