Question #11374

State True or False : If for a given voltage , resistance is changed from R to R/n, power consumed changes from P to nP

Expert's answer

P = V · I = V · V / R = V^2 / R

P0 = V^2 / R

P1 = V^2 / (R/n) = n * V^2 /

R

Answer: true, power consumed changes from P to nP.

P0 = V^2 / R

P1 = V^2 / (R/n) = n * V^2 /

R

Answer: true, power consumed changes from P to nP.
