Question

The five identical bulbs in the following figure are all glowing. The battery is ideal.(What is the order of brightness of the bulbs, from brightest to dimmest? Some may be equal)

What is the order of brightness of the bulbs, from brightest to dimmest? Some may be equal.

Answer “What is the order of brightness of the bulbs, from brightest to dimmest? Some may be equal”.

Circuit Elements Dissipates Electric Power:

The electricity dissipated across the circuit elements is Power = IV, where I is the current and V is the voltage. Two other power formulas are compatible if we want to calculate the power dissipated across resistors or light bulbs: P=I²R and P=V²/R, where R is the resistance.

Brightness is power. The brighter a lightbulb is, the more power it dissipates. The less power dissipated in a light bulb, the dimmer it is.

Bulbs that are connected in series have the exact same current. The voltage drops for all bulbs connected in parallel is the same.

Answer:

The answer is P > S = T > Q = R
