En la figura se muestra un circuito eléctrico. Si los valores de las resistencias R1, R2 y R3 son de 3, 2 y 4 ohmios respectivamente. ¿Cuál es el voltaje que suministra la fuente?

The voltage supplied by the source is 45 V

Explanation:

We note that the resistors are arranged in series, such that the resultant resistor is the sum of the individual resistances as follows

= R₁ + R₂ + R₃ = 3 + 2 + 4 = 9 Ω

The voltage in an electrical circuit is given by the relation;

V = I×R

Where R = = 9 Ω and I = 5 A, we have;

V = I × = 5 A× 9 Ω = 45 V

The voltage supplied by the source = 45 V.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
