The power is quadrupled The power is tripled The power is doubled The power is unchanged The power is sextupledarrow_forwardWhat is the effect when three bulbs are connected in series? The bulb will light up brightly because the current that pass through each bulb are the equal. The bulb will not light up brightly because the current that pass through each bulb are the equal. The bulb will not light up brightly because they shared the voltage that comes from the source. The bulb will light up brightly because they shared the voltage that comes from the source.arrow_forward
- In the given diagram below, which of the two bulbs connected in series will be brighter? Why? Bulb A = R ... Bulb B = 1/2R Bulb A will be brighter because it has greater resistance, therefore greater potential difference and at the same time A greater power. Bulb B will be brighter because it has lower resistance therefore lesser potential difference but greater power. Both bulb A and B will have the same brightness because they are connected in series therefore they have the same current and at the same time same power. Both Bulb A and B will not glow because they have different resistance and the connection is series.arrow_forwardIn circuit below, light bulbs A, B, and C are identical. What will happen when we close the switch S? ε B S A O Brightness of A and C will not be affected.
