Isibonelo semibuzo yokumelana kagesi

Funda futhi ngezinto eziphathelene nokumelana kukagesi , izibonelo zezinkinga zokumelana nochungechunge , izibonelo zezinkinga zokumelana nokuhambisana.

Izibonelo ezimbili zemibuzo yokumelana nogesi

1. Idivayisi kagesi ixhunywe emthonjeni wamandla we-30 Volt futhi ithwala ugesi wama-Ampere ama-2. Nquma ukumelana kukagesi kwedivayisi!

Ingxoxo

Kuyaziwa ukuthi:

I-voltage kagesi (V) = 30 Volts

Amandla kagesi (I) = 2 Ampere

Umbuzo: Ukumelana kukagesi (R)

Impendulo:

Ifomula yokumelana kagesi:

R = V/I

Incazelo: R = ukumelana nogesi, V = i-voltage kagesi, I = ugesi wamanje.

R = 30 Volts / 2 Amps = 15 Volts/Amperes = 15 Ω (funda: Ohm).

2. Bala ukumelana kukagesi kwabaqhubi abaningana abanobude obuyimitha eli-1 kanye nendawo enqamulayo engu-1 x 10^-5 m²Ukumelana kohlobo lomqhubi kushiwo kuthebula elingezansi.

Ifomula yokumelana kagesi:

Incazelo: R = ukumelana kagesi, ρ = uhlobo lokumelana, l = ubude bomqhubi, A = indawo enqamulelayo yomqhubi.
