Question

Can I please get help solving these problems?

In the circuit below, the switch is initially closed. What will happen to the two identical bulbs A and B when the switch is opened? A will get dimmer, B will turn on A will get brighter, B will turn off A will get dimmer, B will turn off A and B will both turn off O A will get brighter, B will turn on

Answer 1

1) Ansules- А Explaination initially difference across will get dimmer, B will turn on when switch is closed, the bulb B will be short circulted since potential bulb B is zo. Hence, complete voltage is consumed is consumed by baltung But when sulitch is open current start flowing through Bulb B. Due to which bulb B turn on and voltage across bulb A decrease due to which it get dimmur 2) By Snell's Land ni sina = m Sin Az 1.5 sin 60 = 1.33 sina, A2: 77.6 deg | Anoncer 3) ES 500 N/C Ad = 10 cm 500 x 10 -) AVE E Ada E 100 Ad 50 volt Ansuler V- 220v Potential difference = 41 P: 100 W, P= v 100) .220 ic i = 0.454 A Ansurer
