What are the four basic units of electricity? provide the variable name and symbol, and unit name and symbol.

The four basic units we use in the topic involving electricity are: 
 
1. Volt (V) - used to express voltages
2. Ampere (A) - used for the electrical current
3. Ohm (Ω) - for electrical resistance
4. Watt (W) - for electric power

For the answer to the question above asking what are the four basic units of electricity?These are the four basic units of electricity: Voltage (V) Current (I) Power (P) Resistance (R)
Well, Ohm's Law states that 'the current drifting in a conductor is directly-proportional to the potential difference across the ends of that conductor, providing all physical conditions, such as temperature, remain constant'. 

As you can see, therefore, only two (not four!) quantities, current, and voltage, are specified. So only two units of measurement apply the ampere and the volt.

I hope my answer helped you. Feel free to ask more questions. Have a nice day!
