What is the voltage across r2 with an input voltage of 5.0v and resistors r1 = 1.5 kiloohms and r2 = 0.5 kiloohms? calculate this value in volts.

1.25 V

Explanation:

Total resistance = R₁ +R₂ = 1.5 +0.5

2 x 10³ ohm.

Current in the circuit = Volt / resistance

=

= 2.5 x 10⁻³ A

Voltage drop across R₂ = Current x resistance of R₂

= 2.5 X 10⁻³ X 0.5

= 1.25 V.

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
