Four (R1 =500 S2, R2 =1000 S2, R3 =1000 S2 and R4 =800 S2) resistors are connected across a battery with open-circuit voltage of 16V, which has an
internal resistance of 200 S2, as is shown in Fig.1. A voltmeter of internal
resistance 2000 12 is connected across the fourth resistor, as is shown in the figure.
What is the reading on the voltmeter? Choose the one correct option.
A 1.90 V
E 4.48 V
B 5.16 V
F 5.80 V
С 3.04 V
G 6.40 V
D 3.88 V
H 1.02 V

.) the observation by semmelweis that more mothers died of childbed fever when their doctors also worked in the morgue

so easy. just google the electromagnetic waves and it’ll pop up.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
