A resistor has a resistance of 50 Ohms. If a 9V battery is connected to it, how much current flows in the wire?
1 answer:
Answer:
0.18 amperes
Explanation:
V = 9
R = 50 ohms
I = ?
Formula
V = I * R
Solution
9 = I * 50 Divide by 50. Switch
I = 9 / 50
I = 0.18 amperes.
If you know what a milliampere is then it is 180 ma which is very large for a 9 volt battery to handle

The loudness was increased by the amplifier which converted electrical energy into sound energy.
I believe the answer is a
V=IR therefore I=V/R=10/50=0.2A therefore the current is 0.2 A
The actual answer is B) Chlorine
According to the Bohr Model diagram, the atom has seventeen electrons. This makes it Chlorine.
