Two 5 volt batteries can be combined or connected in such a way as to render both a +5 volt and -5 volt source within the circuit? True or False?
The time rate of using energy is ________?
In conventional current for the carrier or particle is _____ (positively/negatively) charged?
Homework Answers
1)
**True
As explained in above circuit , I have shown both +5V and -5V arrangements are possible using parallel arrangement of two 5V batteries .
2) Power
Because
Power = Energy / Time
3) Positively charged !!

A typical small flashlight contains two batteries, each having an emf of 1.50 V connected in series with a bulb having a resistance of 18 Ω . A. If the internal resistance of the batteries is negligible, what power is delivered to the bulb? P = B. If the batteries last for a time of 4.1 h , what is the total energy delivered to the bulb? W = C. The resistance of real batteries increases as they run down....

A 12-volt battery is connected to two light bulbs, as drawn in
Figure 1. Light bulb 1 has resistance 3 ohms, while light bulb 2
has resistance 6 ohms. The battery has essentially no internal
resistance, and all the wires are essentially resistanceless,
too.
When a light bulb is unscrewed, no current flows through that
branch of the circuit. For instance, if light bulb 2 is unscrewed,
current flows only around the lower loop of the circuit, which
consists of...
