How do you calculate the voltage of a battery?
1) The battery has a maximum power it can provide. For example, if this power is P = 100 W, then since P = RI^2 the current will be I = (P/R)^0.5 = 31.6 amps and the voltage V = RI = 3.16 V. 2) The battery has a maximum current it can provide. For example, if this current is I = 5 A, then V = RI = 0.5 V.
How do you calculate power in an electric circuit?
We’ve seen the formula for determining the power in an electric circuit: by multiplying the voltage in “volts” by the current in “amps” we arrive at an answer in “watts.” Let’s apply this to a circuit example: In the above circuit, we know we have a battery voltage of 18 volts and a lamp resistance of 3 Ω.
What determines the maximum electrical power a battery can deliver?
The voltage level of the battery determines the maximum electrical power which can be delivered continuously. Power P [W] is the product between voltage U [V] and current I [A]: The higher the current, the bigger the diameter of the high voltage wires and the higher the thermal losses.
How do you calculate battery energy in joules?
The energy in Joules (in watt seconds), is calculated using the following formula; The charge in the battery is calculated using the formula; Where; Qbatt is the charge in the battery in Coulombs (C), Cbatt is the rated Ah of the battery. The total terminal battery bank voltage is calculated using the formula;
How do you find the current of a battery?
The current can be found from Ohm's Law, V = IR. The V is the battery voltage, so if R can be determined then the current can be calculated. The first step, then, is to find the resistance of the wire: L is the length, 1.60 m. The resistivity can be found from the table on page 535 in the textbook. The area is the cross-sectional area of the wire.
How many volts does a battery have?
Now, the battery’s voltage is 36 volts instead of 18 volts. The lamp is still providing 3 Ω of electrical resistance to the flow of current. The current is now: This stands to reason: if I = E/R, and we double E while R stays the same, the current should double. Indeed, it has: we now have 12 amps of current instead of 6.
