If you have to add two alternating voltages how to add them?
A: Alternating voltages means the phase factor must be considered.
When cells are connected in a series?
the cell will add all of the voltages to a lump sum.
How do you sum 3 dc signals to get 1 output?
add the signal voltages by connecting them in series - to +
Does the number of batteries affect the speed of a motor?
If they are connected in series the voltages will add and, theoretically, proportionally speed up the motor.
What is the potential difference that is generated by a battery with a 1.5 V cell in series with a 2.0 V cell?
3.5v You add the voltages when placed in series.
How does number of dry cell affect the strenght of dry cell?
Of each individual dry cell, not at all. If you connect them together in series then their voltages add.
What are the voltages in secondary transmission electric lines?
A: Those voltages are called distribution voltages to differentiate from transmission voltages. And that varies from state to state and locals . Usually around 10kv to 20 kv
Why the graph of breakdown voltage is cheaper than knee voltage?
Break down voltages happens at low voltages (.6 for silicon & .3 for germanium), whereas knee voltages at higher voltages. That's why its cheaper.
What are signals composed of pulses of precise positive voltages and zero voltages?
Digital
Cell phone battery voltages?
Cell phone voltages are DC5V-5.5V
What kind of circuit is one in which all parts are connected in a single loop?
That is a series circuit, all parts have the same current flowing through, and the voltages add up.
Why are batteries sometimes joined in series?
Batteries are connected in series to add their voltages together. For example, two car batteries in series will give twenty four volts.
