Connecting the 10 batteries in series multiplies their voltage while keeping their current the same yielding a 60V 5A configuration. Connecting the 10 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 6V 50A configuration. Using a series-parallel connection, 5 batteries can be connected in series and 5 can be connected in parallel resulting in a 30V 25A configuration.

Ohm's law specifies the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: V = IR.
Solved for current, I = \( \frac{V}{R} \) = \( \frac{600}{60} \) = 10 A

Connecting the 6 batteries in series multiplies their voltage while keeping their current the same yielding a 90V 5A configuration. Connecting the 6 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 15V 30A configuration. Using a series-parallel connection, 3 batteries can be connected in series and 3 can be connected in parallel resulting in a 45V 15A configuration.
Inductance is a factor in which of the following?
determining energy stored by a capacitor |
|
a DC circuit |
|
an AC circuit |
|
batteries connected in serial |
Inductance is a property of an AC circuit (or a component in an AC circuit) that quantifies resistance to changes in current. The current in an AC circuit is continuously changing and inductive reactance (the opposition to change) depends both on the inductance of the circuit or component and the rate at which the current is changing.
Why does current in an electric circuit create heat?
current is naturally hot |
|
voltage is naturally hot |
|
heat is created when the current overcomes resistance in the wire |
|
the wire in the circuit burns when current passes through |
Current in an electric circuit creates heat when the current overcomes resistance in the wire.
