We know V=IR (Ohm's law).
We are given R=180Ω and I=0.1A, then V=(0.1AΩ)(180Ω). Therefore
V=18V
Answer:
because the gravitational pull is maximum at the poles and decreases as it comes down toward the equator.
Answer:
6 V
Explanation:
We can solve the problem by using Ohm's law:
![V=RI](https://tex.z-dn.net/?f=V%3DRI)
where
V is the voltage in the circuit
R is the resistance
I is the current
In this problem, we know the current,
, and the resistance,
, therefore we can find the voltage in the circuit:
![V=RI=(3 \Omega )(2 A)=6 V](https://tex.z-dn.net/?f=V%3DRI%3D%283%20%5COmega%20%29%282%20A%29%3D6%20V)
A barometer is used to measure air pressure!
