A lightning bolt strikes a White Pine tree, depositing 5.0 GJ of energy into it. The potential difference of between the lightning cloud and the tree is 17.0 MV. (a) Calculate the amount of charge (in C) that was produced by the lightning bolt. (b) Calculate change in temperature of the tree if all the energy went into heating the tree. The initial temperature of the tree was 34.0°C. Take the tree to be a cylinder of height 6.0 m, diameter 1.3 m, and density = 460 kg/m3. °C. The specific heat of wood is 2300 J/(kg · °C).
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
