In order to reduce the amount of energy lost due to heat flow, electricity is delivered to our homes using d. low current.

Explanation:

The presence of flow of electrons is said to be electricity. The electricity flows in one direction. The electricity enables function of the electrical devices and machines.

Heat is generated when the electricity flows from one place to another. So the energy is lost in the form of heat.

So to avoid the loss of energy, the electricity is delivered to home using low current. The strength of an electric current can be measured and represented in the unit of ampere.

a. high voltage. To reduce the magnitude of flow of current to reduce loses.

Explanation:

Large power plants have to transmit electricity to consumers via large networks. Transmission over long distances leads to energy losses. Most of the energy loss results from the Joule effect in transformers and power lines. Energy is lost as heat in the conductors. Ohm's law describes how the amount of energy in electricity and its properties (voltage (V), current (I) and resistance (R)) are related. Given by the power (P) = I × V = I × (I × R) = I² × R.

Example: If we want an output of 100 kW, we can do it differently and avoid 100 amperes in the circuit at a voltage of 1000 V. The resistance in the circuit does not change, but the losses in the circuit are now proportional. At 100² × R.

Ohm's Law boils down to the loss scale with the square of the current in a cable. This quadratic factor means that a small jump in current can lead to a sharp increase in losses. If we keep the voltage high, we can keep the current and losses low.

another example of kinetic energy would be,

kinetic energy   >     moving energy
