The voltage at the ends of the battery terminals is 3.6 V. Find the energy consumed by the lamp in 1 minute of glow, if the current in it is 0.25 A.
Initial data: U (voltage at the ends of the battery terminals) = 3.6 V; t (light bulb time) = 1 min (60 s); I (light bulb current) = 0.25 A.
The energy that the lamp will consume during the glowing time is determined by the formula: Q = U * I * t.
Calculation: Q = 3.6 * 0.25 * 60 = 54 J.
Answer: For 1 minute of glow, the light bulb will consume 54 J of energy.
