A 9V battery is connected to a resistor having a resistance of 10 Ω. What is the current and power across the resistor? Solution: I = V/R = 9/10 = 0.9 A P = VI = 9 × 0.9 = 8.1 J/s or 8.1 W Watch the video and solve complete NCERT exercise questions in the chapter Electr...
Potential formula of an arbitrary resistor network has been an unsolved problem for hundreds of years, which is an interdisciplinary problem that involves many areas of natural science. A new progress has been made in this paper, which discovered the pot
specifically for monitoring the power from the battery to the electric motor or for regenerative braking, where they monitor the current in and out of the battery. The new Panasonic Thin Film (ERA Series) and Thick Film Resistor Series (ERJPA-03 Series)...
How can the formula for power (power = work done/time taken) be explained? What is the resistance of a circuit with a power source of 240 V and 3.8 mA? Is AC better than DC? Calculate the voltage required to move 2.6 mA through a 500 K resistor. How much power is produced if a...
Considerable heat is evolved as a result of current passing through the supporting electrolyte.This heat increases with the applied voltage and with increasing ionic strength.Particularly in larger apparatus,despite the circulation of a coolant,this heat produces a temperature gradient across the bed whi...
