What dB change represents a factor of two increase or decrease in power?

How does the total current relate to the individual currents in each branch of a purely resistive parallel circuit?

- It equals the average of each branch current
- It decreases as more parallel branches are added to the circuit
- It equals the sum of the currents through each branch
- It is the sum of the reciprocal of each individual voltage drop
