Na teoria a Lei de Ohm é simples: V = R × I. Mas na prática aparecem algumas diferenças por causa de fatores como: • tolerância do resistor • queda de tensão real no LED • precisão do multímetro Foi exatamente isso que quis mostrar nesse teste. Você já fez esse tipo de medição em bancada? Os valores bateram com o cálculo teórico? #eletrica #multimetro #engenharia #energia #dicasdeeletrica

⚡ Você sabe usar a escala de tensão contínua do multímetro? Muita gente gira o seletor sem saber o que significa DC ou V⎓. Nesse vídeo mostro: 🔹 Como escolher a escala correta 🔹 Como medir tensão de bateria ou fonte 🔹 O erro que muita gente comete 📌 Saber isso evita leituras erradas e diagnósticos errados. Assista até o final e veja na prática! #eletrica #multimetro #eletronica #manutencao #dicastecnicas
