If the current passing through Bulb X is 0.5 A, what is the current passing through Bulb Y? Calculate the voltage drop across Bulb X.

Rubbing the ruler with the cloth transfers electrons from one material to the other via friction. Charging: The ruler becomes electrostatically charged. Teachers frequently deduct marks for missing units

(a) In a series circuit, ( R_t = R_1 + R_2 + R_3 ) = 1 Ω + 3 Ω + 5 Ω = 9 Ω (b) Using Ohm's Law, ( I = \fracVR = \frac99 = ) 1 A (c) For the 3 Ω resistor, ( V = I \times R = 1 \times 3 = ) 3 V
