Question

plz answer me fast I will mark you as brainist.. A lamp of resistance 20 ohm a fan of resistance 25 ohm and a toaster of resistance 15 Ohm are connected in parallel to a 6 volt battery calculate the total resistance be the current through the circuit and potential difference across the speech resistors .​

Answer 1

Total resistance = x

Therefore in parallels,

$\frac{1}{x} = \frac{1}{20} + \frac{1}{15} + \frac{1}{25} = \frac{15 + 20 + 12}{300}$

$= \frac{47}{300} = > x = \frac{300}{47} = 6.38ohms$

Current,I=V/R

=(6×47)/300

=47/50 Ampere
