GEOLOGY

Detailed explanation-1: -The current obtained from a battery is direct current and it flows from the positive terminal to the negative terminal of the battery through an appliance. Its magnitude and direction remains constant with time. Was this answer helpful?

Detailed explanation-2: -DC stands for ‘direct current’ which means the current only flows in one direction. Batteries and electronic devices like TVs, computers and DVD players use DC electricity-once an AC current enters a device, it’s converted to DC. A typical battery supplies around 1.5 volts of DC.

Detailed explanation-3: -Direct current is defined by the constant flow of electrons (see figure 1) from an area of high electron density to an area of low electron density. In circuits involving batteries, this is illustrated by the constant flow of charge from the negative terminal of the battery to the positive terminal of the battery.

Detailed explanation-4: -DC, or direct current, means the electrical current is flowing in only one direction in a circuit. Batteries are a good source of direct current (DC).

Detailed explanation-5: -Batteries produce electricity A chemical reaction between the metals and the electrolyte frees more electrons in one metal than it does in the other. The metal that frees more electrons develops a positive charge, and the other metal develops a negative charge.
