In a circuit, two identical resistances are connected, first in series and then in parallel. the circuit will draw greater current in the first case.

true or false?

False

Explanation:

The current flowing through a circuit can be computed by using Ohm's law:

where

V is the voltage of the battery

Req is the total resistance of the circuit

Let's now compare the two situations. Let's call R the resistance of each resistor (since they are identical, they have same resistance, R)

- Series configuration: in this case, the total resistance of the circuit is given by

So the current through the circuit is

(1)

- Parallel configuration: in this case, the total resistance of the circuit is given by

So the current through the circuit is

(2)

By comparing (1) and (2), we see that the current in the parallel configuration is greater than in the series configuration:

therefore, the correct answer is false.

the amount of current in the coil

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
