Direct current is the flow of current through a current carrying conductor in the same direction from positive to negative ends. Alternating current is the type of current our mains have where the current is constantly changing direction at a certain rate

Explanation:

Direct current  (DC) is a form of electricity that has a unidirectional flow, such that the current path in the current carrying conductor of a circuit is, at all times, in a specific single direction

Alternating Current (AC) is electricity continuously reverses its direction of flow and the magnitude of electricity at a given frequency with time. It is the of current found in electric supply cables that are found in our houses

Therefore, we have;

Direct current is the flow of current through a 1. current carrying conductor in the 2. same direction from positive to negative ends. Alternating current is the type of current our 3. mains have where the current is constantly 4. changing direction at a certain rate

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
