Question

An electric iron of resistance 500 Ω takes a current of 5 A. The heat developed in 1 min is:​

Answer 1

Explanation:

$\purple{\mathfrak{\underline{\large{Given}}}:} \\ resistance(R) = 500 \: Ω \\ current(I) = 5 \: A \\ time(t) = 1 \: min = 60 \: s \\ \blue{\mathfrak{\underline{\large{To \: find}}}:} \\ heat(H) = ? \\ \red{\mathfrak{\underline{\large{Finding}}}:} \\ H = {I}^{2} Rt \\ = {(5)}^{2} \times 500 \times 60 \\ = 750000 \:J \\ \\ \red{\mathfrak{ \large{\underline{{Hope \: It \: Helps \: You}}}}}\\ \blue{\mathfrak{ \large{\underline{{Mark \: Me \: Brainliest}}}}}$
